Well this is brilliant. I installed Zone Alarm Pro and the speed has come up, but only to 0.7 Mb/sec when I should be on 2 Mb. What's more, it has disabled Firefox so I am forced to use IE. The ZA settings for the 2 browsers are identical. I suppose at least I should apologise to ntl for suggesting it was their fault, but at the same time they need to be told that this is becoming a not uncommon problem. I have spent about 4 hours on the phone while they pursued one blind alley after the other.
